DESCRIPTION
This disclosure, its aspects and implementations, are not limited to the specific components or assembly procedures disclosed herein. Many additional components and assembly procedures known in the art consistent with the intended operation and assembly procedures for an electrical box will become apparent for use with implementations of an electrical box from this disclosure. Accordingly, for example, although particular components are disclosed, such components and other implementing components may comprise any shape, size, style, type, model, version, measurement, concentration, material, quantity, and/or the like as is known in the art for such implementing components, consistent with the intended operation of an electrical box.
FIG. 1 shows an electrical box 10 secured to a stud 12 of a house or building. Electrical box 10 includes a rear wall 14 with a top wall 16, a right wall 18, a bottom wall 20, and a left wall 22 each extending forward from rear wall 14 and at least partially defining an electrical box cavity 24. A pair of device securing protrusions 26 extend inward from an inner surface of top wall 16 and bottom wall 20 in a particular implementation. The term device securing protrusion is not limited to securing merely an electrical device, but can be used to secure any suitable connection or apparatus within electrical box cavity 24. Further, an aperture 28 is located within each protrusion 26 and opens proximate a front surface 30 of the electrical box.
A pair of tracks 32 are located along an inner surface 34 of left wall 22 in a particular implementation. Tracks 32 each includes rails 36 extending inward from inner surface 34 of left wall 22. A mounting screw tab 38 is slideable within rails 36 of tracks 32 and includes an angled front surface 40. A mounting screw 42 extends through mounting screw tab 38 and is adapted to secure electrical box 10 to stud 12.
FIG. 2 illustrates electrical box 10 with the mounting screw tab removed and disconnected from stud 12. As can be seen in greater detail, rails 36 of track 32 may be generally u-shaped to provide guidance for the mounting screw tab. An elongated mounting slot 44 is located between rails 36 and may extend for any suitable portion of the electrical box's depth. In one particular implementation, mounting slot 44 is centrally located between rear wall 14 and front surface 30 and extends approximately half of the distance there between. Although the particular implementations are illustrated and described with two mounting slots, any suitable number of mounting slots may be incorporated, including but not limited to a single mounting slot. Further, mounting slot 44 is arranged to receive mounting screw 42 and facilitate securing electrical box 10 to stud 12.
A plurality of teeth 46 are formed in inner surface 34 and may be arranged in any suitable fashion so that the teeth assist in locating and securing the electrical box. In particular implementations, there may be only a single row of the plurality of teeth as seen in FIG. 1, or at least two rows of the plurality of teeth as seen in FIG. 2. Teeth 46 may be located wholly between rails 36 of each track 32 and on the top and bottom of mounting slot 44. In addition, teeth 46 may be arranged vertically so that the mounting screw tab 38 must pass over each tooth as the tab moves forward or backward within electrical box cavity 24.
Referring now to FIG. 3, electrical box 10 has been slide forward in the direction associated with arrow 48 after loosening mounting screw 42 from within electrical box cavity 24 to relieve any compression along left side wall 22. In particular, mounting screw 42 passes through a through hole 50 having a countersunk opening in angled face 40. Thus, mounting screw 42 extends through mounting screw tab 38 and mounting slot 44 at an angle to ensure that the operator can manipulate the mounting screw from within electrical box cavity 24 after drywall or a wall surface has been installed around electrical box 10. Advantageously, this arrangement permits movement of the electrical box in a single plane into and out of the wall along an axis perpendicular to the longitudinal axis of stud 12 when the mounting screw tab is located within track 32 but at least partially disengaged from teeth 46.
Electrical box 10 may also include at least one external guide 52 extending outward from an outer surface 54 of the wall having mounting slots 44 therein. External guides 52 may be molded onto outer surface 54 and located proximate mounting slots 44 to provide additional stability when the electrical box is slide forwards or backwards. Further, external guides 52 ride along a surface 56 of stud 12.
FIG. 4 is similar to FIG. 3, with the exception of the electrical box moved to its rearward most position as indicated by arrow 58. Advantageously, FIGS. 3 and 4 illustrate the total travel of electrical box 10 once installed. Advantageously, mounting screw tab 38 covers mounting slot 44 regardless of the electrical box position to ensure that water or debris cannot enter the electrical box cavity 24.
As seen in FIGS. 3 and 4, the mounting screws 42 are partially disengaged so that teeth 46 on inner surface 34 are disengaged from teeth on mounting screw tab 38 (discussed below). Accordingly, the electrical box can move only in the direction indicated by arrows 48 and 58. In particular, the electrical box movement is limited by mounting screw tabs 38 and rails 36 of tracks 32 which are complimentary shaped to prevent vertical movement, but selectively allow horizontal movement. Still further, when two mounting slots 44 are utilized, the electrical box cannot be rotated once the mounting screws 42 are at least partially installed within stud 12. Finally, when the mounting slots are located on a single side, electrical box 10 can be rotated to mount to stud 12 in any orientation without departing from the box's intended use.
FIG. 5 illustrates the mounting screw tab 38 removed from electrical box 10 with mounting screw 42 in through hole 50. Mounting screw tab 38 also includes a cover portion 60 having a top surface 62 and a bottom surface 64. A plurality of teeth 66 may be molded into bottom surface 64 and are preferably complimentary shaped to teeth 46 on inner surface 34. Cover portion 60 may be sized wide enough to fit within rails 36 while still permitting free movement into and out of cavity 24. Further, cover portion 60 may be long enough to cover mounting slot 44 regardless of the position of the electrical box. Finally, cover portion 60 may have a thickness, meaning the distance between top surface 62 and bottom surface 64, smaller than the thickness of u-shaped rails 36 so that when the mounting screw is disengaged, the mounting screw tab may be moved towards the middle of cavity 24 to disengage teeth 46 and 66 and permit movement in the directions of arrows 48 and 58 (as seen in FIGS. 3 and 4).
Specifically, teeth 46 on inner surface 34 are interlocked with teeth 66 on bottom surface 64 when mounting screw 44 is in the engaged position, or fully seated within mounting screw tab 38 (as seen in FIG. 1). When mounting screw 44 is in the disengaged position, teeth 66 and 46 can be separated and mounting screw tab 38 is slidable within rails 36 (as seen in FIGS. 3 and 4). Thus, when mounting screw 44 is in the disengaged position, electrical box 10 is movable relative to stud 12, mounting screw 44, and mounting screw tab 38.
In accordance with one particular embodiment, after the electrical box is installed on a stud and the drywall or wall board is installed, the position of the electrical box can be adjusted by loosening the mounting screws and pulling the electrical box forward or pushing it backwards.
In accordance with another particular embodiment, a method of adjusting electrical box 10 is disclosed. The steps of adjusting includes providing the electrical box 10 with mounting slot 44 in a side wall and track 32 at least partially surrounding the mounting slot at inner surface 34. Another step is inserting mounting screw tab 38 with through hole 50 within electrical box 10 and inserting mounting screw 42 in through hole 50. Another step is rotating mounting screw 42 in a first direction from within cavity 24 to mount electrical box 10 to stud 12 and prevent relative movement between electrical box 10 and mounting screw tab 38. Still another step is rotating mounting screw 42 in a second direction opposite the first direction from within cavity 24 to permit movement of mounting screw tab 38 with respect to the track and sliding electrical box 10 to a second position. Another step is rotating mounting screw 42 in the first direction from within cavity 24 to lock electrical box 10 in the second position.
It will be understood that implementations are not limited to the specific components disclosed herein, as virtually any components consistent with the intended operation of a method and/or system implementation for an electrical box may be utilized. Accordingly, for example, it should be understood that, while the drawing figures accompanying text show and describe a rectangular electrical box, an electrical box of the present invention may contain any number of sides. Common electrical box shapes also include round, square, and octagonal. However, an electrical box of the present invention may also be other shapes. Components may comprise any shape, size, style, type, model, version, class, grade, measurement, concentration, material, weight, quantity, and/or the like consistent with the intended operation of a method and/or system implementation for an electrical box.
